  This process is a process for production of a vinyl chloride polymer by suspension polymerization or emulsion polymerization of vinyl chloride monomer or a mixture of vinyl chloride monomer with a vinyl monomer copolymerizable with said vinyl chloride monomer in an aqueous medium, characterized in that the polymerization is carried out in a polymerizer, the inner wall surface and portions of the auxiliary equipment thereof which may come into contact with the monomer during polymerization being previously coated with a scaling preventive comprising at least one selected from dyes, pigments and aromatic or heterocyclic compounds having at least 5 conjugated π bonds, while controlling the chloride ion concentration in the reaction mixture to not higher than 100 ppm. According to said process, scaling onto the inner wall surface of a polymerizer, etc. during polymerization can be prevented effectively and surely.

  该工艺是通过氯乙烯单体或氯乙烯单体与可与所述氯乙烯单体共聚的乙烯基单体混合物在水介质中进行悬浮聚合或乳液聚合来生产氯乙烯聚合物的工艺，其特征在于聚合是在聚合器中进行的、内壁表面及其辅助设备中可能在聚合过程中与单体接触的部分事先涂上一层防垢剂，该防垢剂至少包括一种选自染料、颜料和至少有 5 个共轭 π 键的芳香族或杂环化合物的防垢剂，同时控制反应混合物中的氯离子浓度不高于 100 ppm。根据上述工艺，可有效、可靠地防止聚合过程中聚合器等内壁表面结垢。
